中文导读

特立尼达和多巴哥嵌入式工程师逐条反驳 Dmitry Grinberg 的 RISC-V 长批评:核心边界不在 ISA 优劣,在硬件可获得性——买开发板要走美欧分销商,运费 60-200 美元再加关税,一美元的芯片常比本地一节课班费还贵;30 个学生人手一颗 MCU 与 30 人围一块 demo 板的差别就在这条价格边界。Grinberg 自己推导出廉价 MCU 需求、写出 RV32EC 并预言 RISC-V 会统治这块,转头又抱怨这套指令集存在——反驳指出这种抱怨的前提是“硬件能送到你桌上”,而世界多数地方卡在第一步。对 AI 推理算力供应链同样成立:算力变便宜的前提是本地买得到。

为什么值得关注

指令集辩论被略掉的一段:十美分与一美元芯片之间的真实边界是运费与可获得性。

收录理由:给芯片/算力供应链讨论补上“可获得性”视角,对 AI 硬件普惠叙事是必要校正

A Third World Embedded Engineer Responds to "RISC-V: They Should Have Known Better"

August 16, 2026 | RISC-V Article

Dmitry Grinberg published a long piece explaining his distaste for RISC-V, you can read his article here: RISC-V: They Should Have Known Better - Dmitry.GR. It went to the front page of Hacker News and it started a good argument on Lobsters. It is the most substantial criticism the architecture has had in a while and though I switched my entire stack away from STM32 and ARM to RISC-V and did a video on it about a year ago Goodbye STM32 ARM – Meet the CH32 RISC-V Chips That Replaced It! , part of me is infuriated because so much of what he said seems like a biased perspective.

Look, I am not going to defend the ISA committee, RISC-V international denied me membership to their golden tower. On the architecture itself, the compressed store offsets really are strange, Zicsr really should not be a separate thing you have to remember to ask for, I have hit every one of these and I have written a book thats about 80% complete about hitting them on the CH32V003, which is one of the very "RV32E" type chip he mentions.

Maybe I should say where I am writing from, because it changes which parts of this argument look important from my perspective.

I work out of Trinidad and Tobago, a small island nation off the coast of Venezuela. When I want a development board I am not clicking through to next day delivery, I am checking whether the seller ships here at all, what customs will do to it (if I get it at all), and what the total lands at in TT dollars. "Free Shipping" from Digikey, Mouser or any US or European manufactuer dosen't apply to me. I pay anywhere from US $60 to US $200 to ship one dollar chips that people everywhere else get free shipping on. In fact a well known PCB company who reached out to me considering sponsorship turned me down soley based on shipping to my location. Have a look here:

The students I want to teach are in the same position, and so are the ones in Nigeria and Bangladesh and everywhere else the people in the industry does not think about when it writes its blog posts. From that position, the difference between a ten cent part and a one dollar part is not a rounding error and it is not a detail you get to wave past on the way to the interesting discussion about encodings. It is the difference between a class of thirty students each having their own chip and a class of thirty students watching one demo board if any at all. Instruction set elegance is a thing you can affor
